OE NORTHAIVIITON, MASSACHUSETTS, A$$IGNOR TO THE CI-IICOPEE FALLS, MASSACHUSETTS, A CORPORATION STOCK RACK.

Application fi1ed March 21, 1923. Serial- No. 626,578.

This invention relates to storage racks for material supplied in rolls such, for eX- ample, as sheet rubber stock which is commonly stored rolled up between turns of a cloth liner. It has for one object the facilitation of the handling of the stock; for another object the securing of uniform ageing of the stock before use; for another object the avoidance of distorting influences which might cause 'rinkles in the stock; and various other and further objects which will appear from the following specification and claim.

The invention will now be described in connection with the accompanying drawings, in which.

Fig. 1 is a side elevation of a rack embodying the invention; 7

Fig. 2 is an end view thereof; and

Fig. 3 is a detail of a stop.

This invention is designed to avoid the difliculties resulting from the use of the types of rack formerly in use. These former racks either kept the rolls on their ends where the stock would become wrinkled, or required undue handling of the rolls. A further objection to the old types of rack is that there was no insurance that the stock earliest placed in the rack would be used before the stock placed later. For this reason stock newly placed in storage would be used first and the ageing conditions result ing from varying times of storage would be different in different rolls. in the case of uncured rubber, this ageing difference is of considerable importance. By the rack forming the present invention the material is always used in the order in which it is placed in storage, and the ditficulties inherent in. the old racks are avoided.

The rack comprises a frame work indicated generally by 10. Supported in this framework as by gusset plates 11 are channel irons 12 arranged in pairs on opposite sides of the fran'iework to constitute a series of parallel guides or double trackways. As shown the three lower pairs of trackways slant toward the right in Fig. 1, while the upper one slants toward the left. The channel irons serve as runways for disks or rollers 13 each pairof which supports an arbor 14; upon which the roll of stoc-k 15 may be placed. The rollers'on both ends of a stock roll. may be free from the arbor if desired, but it is preferred to have one of them mounted permanently on the arbor, the other being removable, as this prevents displacement of the arbor from the rollers during use. At the upper end of each trackway placed a shelf 16 and at the lower end a similar shelf 17. These shelves serve for loading or unloading platforms on which the rollers and arbors may be inserted or removed from the stock rolls. In order to prevent the rollers from running off the bottom end of the trackway, a stop is provided at the lower end of each track. This stop which is illustrated in detail in Fig. 3 comprises a plate 18 pivoted on a stud 19 mounted on a bracket 20 attached to the frame and shaped so that when in the full line position of Fig. 3 it will project into the path of the rollers on the adjacent track. In order to limit the motion of the stop plate it is provided with a pin 21 which, in the case shown. fits between the flanges 22 of the channel iron forming the frame. By swinging the handle 23 of the plate it can be swung to the dotted line position to release the leading roller on the track.

In use a supply of rollers and arbors is kept on the upper trackway which, it will be remembered, slants to the left in Fig. 1 so that a carrier unit is always present just above shelves 16. When a roll of stock is to be placed in the rack, it is placed on one of the shelves 16 at the left. A. carrier unit comprising an arbor with its two rollers is then taken from the upper trackway, the arbor threaded into the central hole in the stock roll, and the rollers placed in position. The roll can then be pushed toward the right in Fig. 1 until the rollers fall into the trackway. In order to withdraw stock rolls, the stop plates at the end of the trackway are swung to permit one roll to pass, which drops out on the delivery shelf 17. The other rolls will follow down the trackway due to its slanting condition, the one at the bottom coming up against the stop plate which holds it in position. The carrier unit is then withdrawn from the stock roll and placed in assembled condition on the top trackway where it will roll toward the left until it comes in contact with. the units al ready in place.

it wil be seen from the right hand end of the rack, whereas they are placed in the rack from the left, sliding down by gravity to the exit end of the trackway. This not only insures that the stock earliest placed in the rack will be used first, but also permits stock being placed in the rack )y one set of workmen at the same time that others are removing a roll of stock for use, without interference between the two sets.

Having thus described my invention, I claim A stock rack for supplying rolls of material which comprises a. framework, a pair of parallel tracks sloping from one end of the framework to the other and supported thereby, said tracks being spaced apartfurther than the length of the rolls whereby said rol-ls may be supported on the tracks on arbors having end Wheels running in the tracks, a second pair of similar tracks carried by the framework but sloping in the opposite direction, and stops at the lower ends of the trackways, all constructed and arranged so that rolls may be mounted on arbors at one end of the rack, stored upon the first-mentioned tracks, removed from the arbors for use at the other end of the rack, and the arbors returned upon the second-mentioned tracks to the loading end of the rack.
